@jesscss/css-parser
The CSS package exposes Parseman CSS grammar, canonical AST v2 parsing, and explicit CST parsing:
@jesscss/css-parser—parse()to canonical AST v2Stylesheet, grammar, and CST types.@jesscss/css-parser/cst— CST parsing entry.@jesscss/css-parser/grammar— compiled CSS grammar.
The CST and grammar entries expose Parseman types and grammar values. They use
the package's parseman peer; install Parseman when consuming either entry.
The former ./jess Chevrotain/functional-builder surface is deleted. CSS has
no legacy tree parser or construction host. Its public parser constructs the
canonical AST directly through Parseman reductions; the named CST APIs remain
for language-service/document consumers only.
